This patch does not apply to the lucid gwibber source. Please see if the patch can be redone for the current sources. I'm marking this 'patch-needswork', once you have another patch for review, feel free to change the tag to 'patch'

"Thanks for your patch, unfortunately our busy developers haven't been
able to review your patch in a timely manor. The gwibber codebase has
seen significant change and it is likely this patch no longer applies.
Please review it again and if it is still applicable, update it to work
with the latest gwibber trunk. We will be doing a patch review day in
the next few weeks and would like to review your patch. Thanks again for
your contribution!"
